Disclosure of Invention

Technical problem to be solved by the invention

In the drinking container disclosed in patent document 1, the lid body is attached to the upper opening of the sealed container main body together with the O-ring, and has a swingable pouring lid that opens and closes the liquid flow port. A plug body to which a gasket is attached is formed on the pouring cap so as to seal the liquid flow port. Further, the pouring lid can be placed in the lateral direction by providing a locking unit for locking the pouring lid at the closed position. However, if the number of parts such as O-rings and gaskets provided in the drink container increases, the risk of losing them increases, and the cleaning operation and the assembling operation are often troublesome. It should be noted that this problem is not unique to laterally positionable drink containers, but is a common problem with drink containers that require seals such as O-rings, gaskets, and the like.

The invention aims to provide a cover body of a drink container, which is particularly suitable for the drink container capable of being transversely placed and is easy to handle.

Means for solving the problems

A lid according to a first aspect of the present invention is attached to a drink container main body having a peripheral edge portion defining an opening to close the opening, and includes a lid main body, a first seal portion, a second seal portion, and a plug body. The cover body is detachably fixed to a peripheral edge portion of the opening so as to cover the opening. The lid main body has an inner side surface facing the inside of the drink container main body and a peripheral edge portion defining a pouring port for pouring out drink in the drink container main body. The first seal portion is formed integrally with the inner surface, and is configured to be in close contact with the peripheral edge of the opening to seal a gap between the peripheral edge of the opening and the cap body. The second seal portion is integrally formed with the first seal portion in the same material as the first seal portion, and is integrally formed with a peripheral edge portion defining the pouring outlet. The plug is disposed to be movable between a closed position where the plug is in close contact with the second sealing portion to seal the pouring outlet and an open position where the inside and the outside of the drink container main body communicate with each other through the pouring outlet.

A lid body according to a second aspect of the present invention is the lid body according to the first aspect, wherein the first seal portion and the second seal portion are formed of a material different from that of the lid main body.

A cap according to a third aspect of the present invention is the cap according to the first or second aspect, wherein the cap body and the plug are made of resin, and the first seal portion and the second seal portion are made of elastomer. Therefore, the lid body can be configured to be lightweight and hard to deform, and operability in opening and closing the spout can be ensured when the lid body is attached to and detached from the container body. Meanwhile, due to the elasticity of the elastic body, the first sealing part can be attached to the peripheral edge part of the opening of the drinking container body, and the second sealing part can be attached to the plug body, so that the sealing performance can be ensured.

A drink container according to a fourth aspect of the present invention includes: a drink container body having a peripheral edge portion defining an opening; and a lid according to any one of the first to third aspects, attached to the drink container main body.

Effects of the invention

According to the above aspect, the first sealing portion functions as a gasket for sealing a gap between the peripheral edge portion of the opening of the drink container body and the lid body, and the second sealing portion functions as a gasket for sealing a gap between the spout and the stopper body. Further, the first seal portion and the second seal portion are integrally formed of the same material. The first seal portion is formed integrally with the inner surface of the lid body, and the second seal portion is formed integrally with the peripheral edge portion of the spout. Therefore, the number of parts is not increased, and there is no risk of losing the gasket, and handling at the time of cleaning operation, assembling operation, and the like is easy. Further, there is no gap between the first seal portion and the inner surface of the lid body, and between the second seal portion and the peripheral edge portion of the pouring outlet, into which water, dirt, or the like enters, and cleaning is easy.

Detailed Description

Next, a cap and a drink container provided with the cap according to an embodiment of the present invention will be described with reference to the drawings.

< 1. Overview of drink Container

Fig. 1 is an external side view of a drink container 100 according to the present embodiment, and fig. 2 is an external plan view. The drink container 100 is a drink container called a pitcher, a cold water bottle, or the like, and is used for storing drinks such as tea, water, or the like. In addition, the drink container 100 can effectively utilize a limited space in the refrigerator, and can be stored in an empty space in the refrigerator in various postures such as a vertical posture and a horizontal posture. The vertically-oriented posture is a posture in which the bottom surface portion 201 is oriented vertically downward and the spout portion 15 is oriented vertically upward, and the horizontally-oriented posture is a posture in which the side surface portion 202c or 202d is oriented vertically downward and the spout portion 15 is oriented laterally.

The drink container 100 according to the present embodiment includes a container body 200 and a lid 1. The container body 200 is a container having an upper opening. The lid 1 is detachably attached to the container body 200 so as to close the opening of the container body 100. In the following description, the up-down direction and the front-back direction are defined as shown in fig. 1. The direction from the back side of the paper surface to the near side is left, and the direction from the near side to the back side is right. The other drawings will be described with reference thereto.

As shown in fig. 3 (a) and (B), the container body 200 is a container having an upper opening for containing drinks, and includes a bottom surface portion 201 and a cylindrical side surface portion 202 surrounding the bottom surface portion 201. Fig. 3 (a) is a view of the container body 200 as viewed from the front, and fig. 3 (B) is a view of the container body 200 as viewed from the left. The material of each part of the container body 200 is not particularly limited, and may be made of, for example, a hard resin. Further, the container body 200 is preferably formed to be transparent so that the inside can be viewed.

As shown in fig. 2, the bottom surface portion 201 has a substantially rectangular shape. As shown in fig. 3, side surface portion 202 includes: side surface portions 202a and 202b rising straight upward from the front and rear short sides of the bottom surface portion 201; and side surface portions 202c and 202d rising upward while being gently inclined from the left and right long sides. That is, the side surface portions 202a to d are formed in a substantially planar shape. Therefore, the container body 200 is stably erected in a state where the bottom surface portion 201 is vertically positioned downward, and is also stable in a state where the left and right side surface portions 202c and 202d are vertically positioned downward.

A cylindrical portion 203 having a thread groove 203a formed in the outer peripheral surface thereof is continuous with the upper portion of the side surface portion 202. The cylindrical portion 203 is a peripheral edge portion defining an upper opening S1 of the container main body 200. The cylindrical portion 203 is sometimes referred to as a peripheral portion 203 hereinafter. The drink stored in the drink container 100 is injected through the upper opening S1 and is contained in the container body 200. The screw groove 203a is screwed to a screw groove 12a of a lid body 1 described later, so that the lid body 1 can be attached to and detached from the container main body 200.

< 2. Structure of cover body

< 2-1. Integral Structure >

Fig. 4 is a side view of the cover 1. The lid body 1 is configured to cover the upper opening S1 of the container body 200, and includes a lid body 11 and a sealing portion 20 made of an elastic material, which will be described later. The cap body 11 of the present embodiment is made of a hard resin such as polypropylene or ABS resin. The cover main body 11 has: a cylindrical portion 12 having a thread groove 12a on an inner peripheral surface; and a disc-shaped upper surface portion 13 continuous with the upper end edge of the cylindrical portion 12. Then, the lid body 1 can be attached to the container main body 200 by rotating the lid body 1 while matching the screw groove 12a with the screw groove 203 a. The lower surface 14 of the upper surface portion 13 faces the inside of the container main body 200 through the upper opening S1. The lower surface 14 will be referred to as the medial surface 14.

Fig. 5 is a plan view of the inside of the cover 1. As shown in fig. 5, a circular opening S2 is formed in the substantially disc-shaped upper surface portion 13 at a position shifted radially forward from the center thereof. The opening S2 is an opening for communicating the inside and outside of the container main body 200 in a state where the lid body 1 is attached to the container main body 200, and is a pouring port for pouring the drinking material in the container main body 200 into a cup or the like. The opening S2 is defined by a peripheral edge portion 60 formed integrally with the second seal portion 22 described later. The upper surface 22c of the second seal portion 22 constitutes a valve seat 22c described later.

As shown in fig. 2 and 5, the cover body 11 includes a pair of left and right plate-like wall portions 2a and 2b that rise on the upper surface portion 13 and extend in the front-rear direction. The wall portions 2a and 2b have a bilaterally symmetrical structure with respect to a plane passing through the center of the upper surface portion 13 and extending in the front-rear direction and the up-down direction. The opening S2 is disposed between the wall portions 2a and 2b.

A space between the wall portions 2a and 2b accommodates a rocking member 30 and a lock member 40 described later. The locking member 40 is an operation portion to be operated by a user to swing the swing member 30. Then, when the lock member 40 is operated to swing the rocking member 30, the valve body 31 (plug body) coupled to the vicinity of the tip portion 37 of the rocking member 30 swings to open and close the opening S2. The lid body 11, the seal portion 20, the rocking member 30, the lock member 40, and the valve body 31 constitute a part of the lid body 1.

As shown in fig. 5, the lid body 11 includes a spout portion 15 for drinking materials continuous with the front portions of the wall portions 2a and 2b in the vicinity of the opening S2. As shown in fig. 4, the inverted outlet portion 15 is formed with a funnel-shaped slope inclined so as to spread upward from the upper surface portion 13, and a space defined by the slope communicates with the opening S2. Therefore, it is formed that, when the drink container 100 is tilted, the drink flows out from the container body 200 into a cup or the like along this slope of the pouring outlet portion 15. When the opening S2 is closed, the tip portion 37 of the swing member 30 covers the entire spout portion 15, and when the opening S2 is opened, the tip portion 37 of the swing member 30 opens the spout portion 15. Therefore, dust and the like are prevented from entering and contaminating the pouring outlet portion 15.

As shown in fig. 1, the cover body 11 includes a handle portion 50. As shown in fig. 2 and 5, the grip portion 50 continues downward from a rear portion of the wall portions 2a and 2b on the opposite side of the spout portion 15. As shown in fig. 1 and the like, the handle portion 50 is a ring-shaped member having a through hole in the left-right direction, and can be held by a hand of a user. The user can use the handle portion 50 when pouring out the drink through the pouring outlet portion 15, when moving the drink container 100, and the like.

< 2-2. Structure of seal part

Next, the structure of the sealing portion 20 formed in the lid body 1 will be described. The sealing portion 20 is made of an elastic body as described above, and functions as a gasket for maintaining the liquid-tightness of the drink container 100 by elastic deformation. In a state where the lid body 1 is attached to the container main body 200, the seal portion 20 is in close contact with the peripheral edge portion 203 of the upper opening S1, and the gap between the container main body 200 and the lid main body 11 is sealed. The sealing portion 20 is in close contact with a valve body 31 described later to seal an opening S2 serving as a pouring port for drinking. Note that the former sealing performance is achieved by the first sealing portion 21 included in the sealing portion 20, and the latter sealing performance is achieved by the second sealing portion 22 included in the sealing portion 20. The first seal portion 21 and the second seal portion 22, i.e., the entire seal portion 20, are integrally formed of the same material.

Fig. 6 is a bottom view of the cap 1, showing the cap 1 viewed from the side of the inner side surface 14. As shown in fig. 6, two walls 16a and 16b are formed on the inner surface 14 in bilateral symmetry. The walls 16a and 16b each extend radially inward from the vicinity of the inverted outlet portion 15, extend in a semicircular shape around the periphery of the opening S2 toward the grip portion 50, and have a U-turn shape at the tip. Walls 16a and 16b stand upright from inner surface 14 toward container body 200 side below. The second seal portion 22 is substantially cylindrical and is formed integrally with the walls 16a and 16b and a peripheral edge portion 60 (see fig. 8) of the opening S2. As shown in fig. 8, the second seal portion 22 extends radially outward and downward from the spout portion 15 along the peripheral edge portion 60, and then continues to the first seal portion 21. The walls 16a and 16b and the peripheral edge portion 60 are both part of the lid main body 11, are made of hard resin as described above, and are made of a material different from that of the second seal portion 22. However, the second seal portion 22 is integrally formed with these portions of the cap body 11 so as not to be detachable, and a gap is not formed therebetween.

As described above, the first seal portion 21 is in close contact with the peripheral edge portion 203 of the upper opening S1 in a state where the lid body 1 is attached to the container main body 200, thereby sealing the upper opening S1. Therefore, the first seal portion 21 is substantially annular and has an outer diameter substantially equal to the peripheral edge portion 203 of the upper opening S1. The first seal portion 21 extends in the vicinity of the outer periphery of the inner side surface 14 in the circumferential direction, and is formed integrally with the inner side surface 14. The upper surface portion 13 having the inner surface 14 is a part of the cap body 11, is made of a hard resin as described above, and is made of a material different from that of the first seal portion 21. However, the first seal portion 21 is integrally formed with the upper surface portion 13 of the cap body 11 so as not to be detachable, and no gap is formed between the first seal portion 21 and the inner surface 14.

As described above, the seal portion 20 is formed integrally with the lid main body 11 as a part of the lid body 1. Therefore, water, dirt, and the like do not enter between the seal portion 20 and the cover main body 11, and cleaning is easy.

Fig. 7 (a) is a bottom view of the seal part 20, and fig. 7 (B) is a sectional view taken along line I-I of fig. 7 (a). As shown in fig. 7 (a), the second seal portion 22 is formed to extend continuously radially inward from the inner peripheral portion of the first seal portion 21. Note that the surface facing the inside of the container body 200 when the lid body 1 is attached to the container body 200 is referred to as the lower surface of the seal portion 20, the lower surface of the first seal portion 21 is referred to as 21a, and the lower surface of the second seal portion 22 is referred to as 22a, respectively. As shown in fig. 7 (B), the lower surface 21a and the lower surface 22a do not coincide in position in the vertical direction, and the lower surface 22a is located at a higher position in the vertical direction than the lower surface 21 a. The two arm portions 23a and 23b extend in a shape corresponding to the walls 16a and 16b at a position of the second seal portion 22 deviated by substantially 180 ° from a portion continuous to the first seal portion 21. A notched portion 24 is formed in the up-down direction between the arm portion 23a and the arm portion 23b, and the lower surface 22a at the position of the notched portion 24 is located at a higher position in the up-down direction than the lower surface 22a at the other portion. In other words, at the portion of the notch portion 24, the thickness of the second seal portion 22 is thinner than the other portions. On the other hand, as shown in fig. 7 (B), the thickness of the first seal portion 21 is substantially constant in the entire circumferential direction.

The second seal portion 22 is substantially cylindrical, and as shown in fig. 7 (B), a recess 25 is formed in the outer peripheral surface 22B, and an upper surface 22c is provided on the side opposite to the lower surface 22a. The upper surface 22c functions as a valve seat of the valve body 31 described later. Hereinafter, the upper surface 22c may be referred to as a valve seat 22c. The recess 25 is formed over the entire circumferential range. The thickness of the second seal portion 22 is substantially constant in the entire circumferential direction except for the portion of the notch portion 24. The lower surface 22a of the second seal portion 22 is formed to extend radially inward from the vicinity of the upper surface of the first seal portion 21.

Fig. 8 shows a detail of a cross section near the opening S2 of the lid main body 11 forming the spout. Shown in solid lines is the cap body 11 and shown in broken lines is the seal portion 20. In addition, for reference, the cylindrical portion 203 of the container main body 200 is shown by a chain line. The second seal portion 22 is formed to be in close contact with the peripheral edge portion 60 while receiving the convex portion 62 of the peripheral edge portion 60 in the concave portion 25. Note that although the opening S2 defined by the peripheral edge portion 60 forms a pouring port for drinking materials, the second seal portion 22 is present along the inner periphery of the peripheral edge portion 60, and therefore the pouring port through which liquid actually flows is a space one time smaller than the opening S2. From this viewpoint, it can be said that the opening S (pouring outlet) is defined by the second seal portion 22.

As shown in fig. 8, the upper surface of the upper surface portion 13 is formed flush with the valve seat 22c of the second seal portion 22. On the other hand, the inner surface 14 of the cover main body 11 is flush with the lower surface 22a of the notch 24 of the second seal 22. The lower surface 22a other than the notch 24 is flush with the lower ends of the walls 16a and 16b.

When the screw groove 12a of the lid body 1 is fitted to the screw groove 203a of the container main body 200 and the lid body 1 is rotated, as shown in fig. 8, the lower surface 21a of the first sealing portion 21 comes into contact with the upper end of the cylindrical portion 203 of the container main body 200. When the screw structure including the screw groove 12a and the screw groove 203a is tightened, the upper end of the cylindrical portion 203 is slightly recessed into the lower surface 21a of the first seal portion 21. That is, the lower surface 21a of the first sealing portion 21 is in close contact with the upper end of the cylindrical portion 203, and the upper opening S1 of the container main body 200 is kept liquid-tight. On the other hand, when the opening S2, which is a spout for drinking, is closed, as shown in fig. 4, the upper surface 22c of the second seal portion 22 is in close contact with the lower end of the cylindrical valve body 31 described later, and the opening S2 is kept liquid-tight. That is, according to the above configuration, the sealing portion 20 formed in the lid body 1 can function as a gasket for sealing not only the upper opening S1 of the container body 200 but also the opening S2 formed in the lid body 1.

< 2-3. Structure of locking mechanism

Next, a lock mechanism that can open and close the opening S2 as a spout and can lock a closed state and an open state of the opening S2 will be described. The opening S2 is opened and closed by a swingable rocking member 30 constituting a part of the lid body 1. As shown in fig. 5, the rocking member 30 is disposed so as to be sandwiched between the wall portions 2a and 2b in the left-right direction. The rocking member 30 of the present embodiment is made of a hard resin such as polypropylene or ABS resin, as in the case of the cover body 11.

As shown in fig. 4 and 5, the swing member 30 includes a substantially plate-shaped main body 30a, and the main body 30a extends in the front-rear direction so as to cover the top of the spout portion 15 to the upper side of the grip portion 50. A cylindrical valve body 31 is attached near the front end 37 of the body 30a. The valve body 31 is disposed on the lower surface of the body 30a such that the central axis extends in the vertical direction. In the present embodiment, the valve body 31 is formed integrally with the body portion 30a. The valve body 31 opens and closes the opening S2 in accordance with the swing of the swing member 30. In the state shown in fig. 4 and 5, the body 30a is positioned substantially horizontally, and the lower end of the valve body 31 abuts against the upper surface 22c of the second sealing portion 22 to seal the opening S2. Here, a state in which the opening S2 is sealed by the valve body 31 is referred to as a closed state, and a state in which the opening S2 is opened is referred to as an open state.

Fig. 9 (a) is a side view showing the inside of the rocking member 30 in perspective, and fig. 9 (B) is a bottom view of the rocking member 30. As shown in fig. 9, the rocking member 30 has a pair of left and right columns 34a and 34b extending left and right on the rear end portion 33 of the main body 30a. The central axes of the columns 34a and 34b coincide. The right column 34a has a shape obtained by cutting out a part of a circular column when viewed from the left-right direction, and the cut-out part forms a concave portion 35a recessed in an arc shape. Note that the rocking member 30 has a bilaterally symmetrical shape as a whole. Therefore, the left column 34b also has a shape bilaterally symmetrical to the right column 34a, and similarly has the recess 35b. The concave portions 35a and 35b are configured to receive the tips of convex portions 43a and 43b of the lock member 40 (see fig. 12 a). A pressed portion 36 that is curved substantially about the columnar bodies 34a and 34b in a side view is formed on the upper surface of the rear end portion 33 of the body portion 30a.

As shown in fig. 9, the swinging member 30 has a hook-shaped claw portion 32 extending downward from the main body portion 30a in the vicinity of the center in the front-rear direction as a fulcrum portion for swinging. The claw portion 32 is configured to be engaged with a spherical claw portion 17 (see fig. 4), and the claw portion 17 extends upward from a base portion 17a rising from the upper surface portion 13 between the wall portions 2a and 2b. The claw portion 32 can slide around the claw portion 17 along the surface of the claw portion 17. The rocking member 30 can rock as the claw portion 32 slides on the surface of the claw portion 17, while using the point where the claw portion 32 engages with the claw portion 17 as a fulcrum.

The rear end 33 of the rocking member 30 is supported by the locking member 40. The locking member 40 is a member operated by a user to swing the rocking member 30. As shown in fig. 1, the lock member 40 is configured such that, in the external appearance of the drink container 100, only a part of the lever portion 41 included in the lock member 40 protrudes from the rear of the handle portion 50 and the wall portions 2a and 2b above the handle portion. The positional relationship between the lever portion 41 and the grip portion 50 is such that the user can just touch the thumb when gripping the grip portion 50. The lock member 40 of the present embodiment is made of a hard resin such as polypropylene or ABS resin, as in the case of the cover body 11.

Fig. 10 (a) is a plan view of the lock member 40, and fig. 10 (B) is a left side view of the lock member 40. The lock member 40 has a bilaterally symmetrical shape as a whole, and has: a side wall 40a rising upward from the right end of the lever portion 41; and a side wall 40b rising upward from the left end of the lever portion 41. In front portions of the side walls 40a and 40b, projections 43a and 43b having arc-shaped distal end portions in a side view are formed, and these distal end portions are received in the recesses 35a and 35b of the rocking member 30, respectively. A space T1 is formed between the side walls 40a and 40b in front of the lever portion 41. The distance between the side walls 40a and 40B is wider than the width of the rear end portion 33 of the rocking member 30 in the left-right direction, and the rear end portion 33 of the rocking member 30 enters the space T1 as described later (see fig. 12B).

At the rear portions of the side walls 40a and 40b, convex portions 45a and 45b are formed at a distance rearward from the convex portions 43a and 43b constituting the front portions of the side walls 40a and 40b, respectively. In the closed state of the opening S2 as shown in fig. 12 (a), the convex portions 43a, 43b, 45a, and 45b all protrude upward. Further, a groove portion 42a having a bottom 46a is formed between the right convex portions 43a and 45a as shown in fig. 10. Similarly, a groove 42b having a bottom 46b is formed between the left convex portions 43b and 45b. In the open state of the opening S2 as shown in fig. 12 (B), the upper end of the lever portion 41 functions as a pressing portion 47 that holds the pressed portion 36 of the rocking member 30.

As shown in fig. 10 and 12, the lock member 40 has a cylindrical shaft portion 44 between the side walls 40a and 40b, more specifically, between the convex portions 43a and 43 b. Shaft portion 44 is received by a bearing portion 51 formed between wall portions 2a and 2b at the upper end of handle portion 50. The bearing 51 has a shape obtained by cutting out an upper portion of a cylinder having a central axis extending in the left-right direction, and the shaft 44 is inserted into an internal space defined by the bearing 51 through the cutout. By pushing up or pushing down the lever 41, the lock member 40 can swing about the shaft 44 engaged with the bearing 51 as a rotation axis. Note that the direction in which the lever portion 41 is pushed up refers to a direction in which the spool 31 is away from the valve seat 22c (clockwise in fig. 12). In contrast, the direction in which the lever portion 41 is pushed down is a direction in which the valve body 31 approaches the valve seat 22c (counterclockwise direction in fig. 12).

Fig. 11 is a rear view of the lid body 1 in the closed state. The lock member 40 is disposed below the rocking member 30 so as to be sandwiched between the wall portions 2a and 2b in the left-right direction together with the rocking member 30. Further, as shown in the drawing, a plurality of notches are formed in the lever portion 41 in the left-right direction, so that the user's fingers are not easily slipped and the user easily transmits force to the locking member 40.

Fig. 12 (a) is a side view of the water stop mechanism in a closed state of the see-through opening S2. In the closed state, the main body portion 30a of the rocking member 30 is horizontally supported from below by the claw portion 17 and the convex portions 43a and 43b of the lock member 40. The protrusions 43a and 43b support the rear end 33 of the rocking member 30 and engage with the recesses 35a and 35b of the rocking member 30 to lock the rear end 33. The lock is not released unless an external force of a degree that elastically deforms the cylinders 34a and 34b and the protrusions 43a and 43b more than a certain degree acts through the lever portion 41. Thus, even when the drink container 100 is placed with the side surface portion 202c or 202d of the container body 200 directed vertically downward, the valve body 31 can be continuously brought into close contact with the valve seat 22c, and the liquid-tight state of the opening S2 can be maintained.

Fig. 12 (B) is a side view of the water stop mechanism locked in the open state in the see-through state. In order to unlock the closed state and open the opening S2, the user applies a force of pushing up the lever portion 41 with the thumb of his or her hand while holding the grip portion 50 with one hand. Then, the lock member 40 starts rotating about the shaft 44 as a rotation axis, the engagement between the concave portions 35a and 35b and the convex portions 43a and 43b is released, and the swing member 30 starts swinging so that the rear end portion 33 faces downward and the valve body 31 faces upward. When the lever portion 41 is further pushed up, the rear end portion 33 of the rocking member 30 enters the space T1 between the side walls 40a and 40b of the locking member 40. At the same time, the posts 34a and 34b of the rocking member 30 enter the groove portions 42a and 42b of the locking member 40, respectively. When the lever 41 is pushed up to the position where the pressed portion 36 of the rocking member 30 is pushed up by the pressing portion 47 of the locking member 40, the posts 34a and 34b are engaged with the innermost bottom portions 46a and 46b of the groove portions 42a and 42b and locked. Thus, the rocking member 30 can be held in a state where the opening S2 is opened.

< 3. Method for using drinking vessel

When drinking materials such as tea and water are stored in the drinking material container 100 provided with the lid body 1, first, the lid body 1 is rotated to detach the lid body 1 from the container main body 200. Then, the drink is injected into the container body 200 through the upper opening S1 of the container body 200. After pouring the drink, the cap 1 is rotated in the opposite direction to the previous one, and the cap 1 is firmly fixed to the container body 200.

At this time, the container body 200 is kept liquid-tight by the sealing mechanism and the locking mechanism. Therefore, the drink container 100 does not allow drink in the container body 200 to leak to the outside even if it is placed laterally, for example. Therefore, even if there is no space for longitudinally placing the drink container 100 in the refrigerator, it can be accommodated in the refrigerator in a laterally placed posture. Note that, as shown in fig. 2, the width of the lid body 1 in the left-right direction falls within the range of the width of the container main body 200 in the left-right direction. Therefore, the substantially planar side surface portions 202c and 202d can be placed in a stable state in the lateral direction by being directed vertically downward.

When taking out the drink from the drink container 100, the user first holds the handle 50 and pushes up the lever portion 41 protruding rearward from the handle 50 with the thumb of his hand. Then, a click sound is generated to confirm that the posts 34a and 34b of the rocking member 30 are locked to the grooves 42a and 42b of the lock member 40, respectively, and the thumb is separated from the lever portion 41. Then, the drinking container 100 is tilted while holding the handle portion 50, and the drinking is poured into a cup or the like through the pouring outlet portion 15. When the pouring is completed, the grip of the grip portion 50 is maintained and the thumb of the hand applies a downward force to the lever portion 41, thereby releasing the locked state. When the lever portion 41 is depressed with the thumb to level the rocking member 30 and the convex portions 43a and 43b of the locking member 40 are locked to the concave portions 35a and 35b, the valve body 31 comes into close contact with the valve seat 22c to seal the opening S2. As a result, the container body 200 is again kept liquid-tight, and can be stored in a refrigerator in various postures.

When the drink container 100 is cleaned, the user rotates the lid 1 and removes the lid 1 and the container body 200. As a result, the lid body 11 and the sealing portion 20 can be easily cleaned together from the inner surface 14 side of the lid body 1. The container body 200 can be directly cleaned by inserting a hand or a sponge with a handle into the container body 200 through the wide upper opening S1.

< 4. Feature >

(1)

In the above embodiment, the first seal portion 21 functions as a gasket for sealing the upper opening S1, and the second seal portion 22 functions as a gasket for sealing the opening S2. Further, the first seal portion 21 and the second seal portion 22 are integrally formed of the same material, and are also integrally formed with the cap main body 11 of a different material. Therefore, it is not necessary to provide a gasket for sealing the upper opening S1 and a gasket for sealing the opening S2 as separate members of the lid body 11, and it is not necessary to provide a gasket when attaching the lid body 1 to the container body 200. Further, there is no gap into which water, dirt, or the like enters between the first seal portion 21 and the second seal portion 22 and the cover main body 11. Further, since the lid body 1 and the seal part 20 can be cleaned at the same time during cleaning, the cleaning operation is simplified, and the time and effort for removing the gasket and cleaning the gasket one by one is released. Moreover, the risk of losing the gasket removed during cleaning is eliminated. Further, since the first seal portion 21 and the second seal portion 22 are formed of the same material and are continuous with each other, the material can be simultaneously poured into a molding die or the like in the molding step of the seal portion 20, and the molding step can be simplified.

In the above embodiment, when the lever portion 41 is pushed up by an operation, the swing member 30 swings to open the opening S2 as the spout. That is, the pouring outlet can be opened by an operation of pushing up the lever portion 41. Therefore, even if an object or the like accidentally comes into contact with the rear end portion 33 of the rocking member 30, the risk of opening the spout by mistake can be reduced.

In the above embodiment, the lever portion 41 is disposed below the rear end portion 33 of the rocking member 30, and the valve body 31 is disposed on the side of the front end portion 37 with respect to the fulcrum portion of the rocking member 30. When viewing the rocking member 30, the user intuitively thinks that the rocking member 30 is rotated in a direction of pushing up the valve body 31 from the valve seat 22c, that is, the user presses down the lever portion 41, in order to move the valve body 31 to the open position. However, the spout is opened by operating the lever portion 41 in a direction opposite to the operation direction intuitively thought as such. Therefore, the user is encouraged to consciously act, and the user is easily prevented from opening the spout by mistake.

The lid body 1 of the above embodiment is provided with the sealing portion 20 and a lock mechanism capable of locking the sealed state of the pouring outlet, thereby enabling the drinking container 100 to be placed in a lateral direction.
